Effect of Water-Based Polyurethane Film-Forming Agents on the Performance of Continuous Basalt Fibers

  • 摘要: 以聚醚醇与二异氰酸酯为主要原料、N-甲基二乙醇胺(MDEA)为亲水扩链剂合成了应用于连续玄武岩纤维浸润剂中主成膜剂的水性聚氨酯。采用激光粒度仪、热失重分析仪等表征了水性聚氨酯粒径大小、热力学性能等;用傅里叶红外光谱仪、万能试验机、扫描电镜等表征了浸润剂处理前后连续玄武岩纤维的表面化学元素组成、力学性能、表面形貌变化等。探究MDEA质量分数(w(MDEA))对水性聚氨酯以及连续玄武岩纤维性能的影响,浸润剂处理前后的连续玄武岩纤维耐酸、碱性等。结果表明,当w(MDEA)=6.0%时,水性聚氨酯稳定性较好,浸润剂处理过的连续玄武岩纤维断裂强度提升到175%,耐酸、碱腐蚀性明显增强。
